The movie will have plenty to draw from; Mike Tyson exploded onto the boxing scene in the late 80s and was known for his quick and violent knockouts. After winning 16 of his first 28 fights with first-round knockouts, Tyson won the WBC Heavyweight title in 1986.
Tyson held onto his titles until a stunning loss in 1990, and soon after his life went into a freefall. He was tried and convicted of rape and spent three years in prison.
Tyson made a bit of a comeback after he released from prison, until his infamous ear-bite during a fight with Evander Holyfield in 1997. In 2002, he filed for bankruptcy.
The film has no studio, but Variety feels finding won't be an issue considering the talent involved. We're inclined to agree.
